Copper Electrowinning Process
Jun 23, 2021 · Copper electrowinning is based on the copper electrolysis principle which uses electrical power to reduce copper ions in solution to the copper metal on the cathode and to oxidize water on the anode in oxygen gas and hydrogen ions. The chemical equation (a) gives the copper electrolysis global chemical reaction.

Copper electrowinning: theoretical and practical …
For the winning of copper by the addition of electrons  Cations go towards the cathode, and anions go to the anode. The working electrode is where reduction takes place and the counter electrode is where oxidation occurs. The working electrode is the cathode and the counter electrode the anode. For the general oxidation/reduction reaction:  Faraday’s Law gives … File Size: 3MB Page Count: 28

Alternate Anode Reaction for Copper Electrowinning
The conventional copper electrowinning process uses the water hydrolysis reaction as the anodic source of electrons. However, this reaction generates acid and oxygen gas. The oxygen, which leaves the system, is associated with some acid from the electrolyte resulting in an acid mist.
